Interference Effects in Auger Resonant Raman Spectra of CO via Selective Vibrational Excitations Across the O 1s -2? Resonance

Abstract
The Auger resonant Raman spectra of CO, arising from the transitions to the X and A final electronic states of CO+, have been recorded at photon energies corresponding to the vibrational excitations v[prime]=3,5, and 8 in the O 1s-->2pi resonance. The spectra are simulated within the model that takes into account both the lifetime-vibrational interference (LVI) and interference with the nonresonant photoemission. The spectroscopic parameters, omegae, omegaexe, Gamma and re, of the O 1s–12pi core-excited state, necessary for the simulation, have been derived by fitting the Franck-Condon simulation to the total ion yield spectrum, assuming a Morse potential for the O 1s–12pi state. Not only the LVI but also the interference with the... (More)
